i started with semis, and tried out revolvers later. i have to say, the grip angle on a revolver throws me. i don't want to have to try to become comfortable with two vastly different grip angles. even the glock grip angle annoys me. for this reason, i sold all of the revolvers i ever bought.

as to steel/alloy vs polymer, i always prefer to shoot a steel/alloy, but you can get a few more rounds in a smaller poly gun than you can in steel.
